exhaust standards?

[zed]

I get the AMA letter and this was in it, thought I'd share in case some didn't get it.

New stationary on-highway motorcycle sound test standard released by the Society of Automotive Engineers International (SAE): The SAE has produced a simple, consistent and economical sound test standard that can be used to determine whether a streetbike (on-highway motorcycle) exhaust system emits excessive sound, the AMA reports. The procedure is the result a long-term project of the Motorcycle Industry Council and the Society of American Engineers. The J2825 "Measurement of Exhaust Sound Pressure Levels of Stationary On-Highway Motorcycles," issued by the SAE in May 2009, establishes instrumentation, test site, test conditions, procedures, measurements and sound level limits. According to the SAE, the J2825 standard is based on a comprehensive study of a wide variety of on-highway motorcycles.
The creation of a new street motorcycle sound measurement procedure was a top recommendation of the 2003 National Summit on Motorcycle Sound, expressed by its Motorcycle Sound Working Group. The AMA organized the National Summit on Motorcycle Sound to pull together riders and user organizations, representatives of the motorcycle manufacturers, the aftermarket industry, racing promoters, government agencies, and others to develop proposals regarding the increasingly controversial issue of excessive motorcycle sound.
The SAE J2825 standard can be downloaded on the SAE website for a fee of $48.80 - $61.00 at: http://www.sae.org/technical/standards/J2825_200905

Boston, Massachusetts: In an attempt to silence community concerns regarding excessive motorcycle exhaust sound, the Boston City Council fast-tracked enactment of Docket 0658 (An ordinance regulating the noise levels of motorcycles) on June 3, 2009. A public hearing was held May 26 before the Committee on Government Operations. The new ordinance mandates that all on-highway motorcycles built after December 31, 1982 must have either OEM (original equipment manufacturer) or aftermarket exhaust systems that comply with the US EPA labeling provision in the Code of Federal Regulations. Violations will result in a $300 fine.
